Digg is getting in on the act, launching separate Twitter accounts that you can follow for each of their different news sections. Each time a story reaches the Digg front page, it will be broadcast to one main account - Digg Homepage – as well as to the account representing the category the item was in, like Technology, Science, or Offbeat.
Of course, this could already be accomplished if you use an RSS reader by subscribing to the feeds Digg offers for each section, but for the millions of people that don’t do so, following Twitter accounts is a nice and easy alternative. It also means that perhaps you can unfollow Twitter accounts for individual blogs and let Digg act as your filter, but we highly discourage such behavior :)
